Abstract

Procedure for obtaining quinazolines, characterized in that halogenated derivatives of the general formula are reacted: R1 - CCl2- N = CCl - R2 wherein R1 and R2, which are the same or different, mean chlorine, lower aliphatic moieties, lower alkyl halogen moieties, aromatic moieties, optionally substituted, or heterocyclic moieties, optionally substituted, with 5 or 6 members, where R1 It can also mean hydrogen, with aromatic amines or their salts at a temperature between 0-200ºC and preferably between 60-160ºC.
